General Description
Features
AZ339
The AZ339 series consists of four independent preci- _{· Wide Supply Voltage Range}
sion voltage comparators with an offset voltage speci-
- Single Supply: 2.0V to 18V
fication as low as 2mV. The input common mode
- Dual Supplies: ±1.0V to ± 9V
voltage range of these comparators includes ground, _{· Very Low Supply Current Drain: 0.8mA}
even when operated from a single power supply volt-
age. Operation from split power supplies is also possi-
ble and the low power supply current drain is
